lily invention relates to a i improvement in railroad track construction, the object bein f to so construct the track that the rails will be supported throughout their entire length by connected girders, thereby perinitting' the use of smaller rails, than can safely be used on a. track in which he rails are siipportet at intervals on the ties.

With this and other objects in 'vie'w' my invention consists in the pa and combinations of pet will be more fully plained and pointed out in the claims.

The bottom of the seat is himei'cr slightly wider than the Width of the head of a rail so as to permit the latter to rest well down toward the bot tom of the depression as will be hereinafterexplained.

the chairs 5, each of which consists of two side members connected by two f the latter being integral with the si bers and dependin at opposite side tie. These chairs are located so 3 side members thereof are at epposie of the depressed seat, and the yolzes 6, ere te -(l slightly below the bottom the seat so as not to interfere with the girder 7 which rests Within said seats. Each side member of a chair consists of a base 8, end plates 9, inner wall 10 and a top shoulder 11 all formed integral. Each base plate 8 is straight on its lower t adjacent outer end, so as to rest solitly on the fist upper face of the tie, and is thickened and curved at its inner end so as to conform to the curvature of the side \Tflll of pressed seat. The end pl Well 10, support the top c letter is slightly inclines provided with HUM flange which'holds the lateral movement and, or from spreading:

Any other form or girder -will how. 1' answer the purpose, but ll prefer rolls, on account not only of their eheopness, but also because of the superior quality of metal from which they are made. The girders l are. upproxinmtely the depth of the from the shoulders 11 so mately fill the space between tr bers of the chair, and are sus and preferably Wholly suppor shoulders 11 of the chairs. These support the rails throughout the 1 the latter, except possibly at switches, are arranged to break joints with the ran 5 so that a joint in the rails,- and a joint in the girders will not come between the sameties. The ends of the girders are connected by fish plates 16, and the ends of the mils 15 are connected by fish plates 17, and the connected rails and also the girders are restrained egeinst vertical movement by the spring clips 18 which lutler engage ribs 19 on the underside of the shoulders 11, on the tan chairs, and hear adjacent the upper ends on v the to edge of the flanges 32, the free upper edges of the clips overhanging the base flanges of the rails without contacting with the same, thus leaving the rails and girders loosel seated on the chairs and free to move lengthwise without opposition, and also free to move vertically a limited distance. The only pressure'to which a rail is subjected other than downward, is an outward one which is taken care of by the sideflanges 12 of the chair, hence there is theoretically, no tendency of the rails to tip, but as the ends of the clips overhang the base flanges of the rails and are only removedtherefrom a limited distance, it will be seen that tipping to anything like a dangerous extent would be absolutely prevented by the ends of the clips. The clips shown are of spring metal sprung into place on the chair, and are carried solely by the chairs but it will be clearly evident that instead of using spring metal clips, I may use rigid stops securcd to the chair and o erhanging the base flange of the rail, hence it would have it understood that my invention herein shown, is just as well adapted for use with rigid overhanging stops as it is for the Ll-shape spring clips he; shown and described.

"notion above described, wherein the are pported on connested giro the load is distributed eoually on and between all the ties, and by i old rail instead of built up girders all objection to riveted structure is avoided. By supportil'ig the rails on suspended girda lighter rail can do the work of a much heavier rail that is supported at intervals on ties. The larger the rail the softer the head thereof. This is due to the inability to work it sulliciently to harden it. @Vith these improvements smaller rails supported throughout their lengths and at their ends, can be safely used with the heavy rolling: stool; that is now rapidly coming" into use, l WlilCl'i could not be used if they were supported only at intervals.

By the use of the stringers in conjunction with the or ties, l distribute the rolling load very uniformly over the cross ties; considorahl y reduce the pressure per square feet between the ties and the ballast and also reduce the cost of maintaining the road boil owing to the fact that less re-tainpwill be required. This is very essential as there must be at least twelve inches be tween ties, {which are approximately eight inches base widths) for taniping, and as the ties are about twenty inches apart from'centor to center, there is no room for additional use of the stringers the load will be distributed. over a greater nunihcr of ties, and as the rails themselves are not of strength sutilcient to distribute load, the

1,1 races use of old or new rails in the form of stringers with the rails resting on top of the latter, form in effect a, bridge for carrying the load over and onto several ties.

While 1 prefer to provide the ties with depressed seats and have so shown them, the depression may be dispensed with and the chairs constructed to support the stringers above the top surface of the ties.

Vvhen it is necessary to insulate the rails from the ties, it may be conveniently done as shown in Fig. 5, by providing the chair with a removable shoulder 20 and flange 21, and inter-posing insulating material 22 be tween said shoulder and flange and the chair proper, and also interposing insulating material 23 between the chair and the armor plate 24: against which the lower end of the spring clip bears.

it is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence ll would have it understood that I do not wish to confine myself tothe exact construction arid arrangement of parts shown and described, but

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is
